On the other hand, it is also a model of the organization of the genes in transcription units, operons and simple and complex regulons.

Note: A complex operon with several promoters contains, therefore, several transcription units.

Given the definition of an operon , at least one transcription unit must include all the genes in the operon.

As a result, the enzyme is released, and the distal regions of the transcription unit are never transcribed.

As a result, transcription of all five late transcription units begins at the same point in the viral reproductive cycle.

Microsatellites are often found in transcription units.

These sites are located at different relative positions in their respective transcription units.

The antitermination protein pN acts specifically on the immediate early transcription units.

Earlier studies on chromosome 21 and 22 showed the power of tiling arrays for identifying transcription units.

However, they have not yet been sequenced or mapped on the transcription unit.
